Расскрой скобки: -5*(3x+7-t) (1.2a+3.4b+2)*3 -(4a-5b-3) a(3x-y+z) 2a(x-3y+2z) -6(2/3x-1/2y+1/4z)

-15х-35+7t
3.6a+10.2b+6
-4a+5b+3

2ax-6ay+4az
-4x+3y-1.5z

-5*(3x+7-t) = -15x-35+5t=5t-15x-35
(1,2a+3,4b+2)*3=3,6a+10,2b+6
-(4a-5b-3)=-4a+5b+3=5b-4a+3
a(3x-y+z)=3ax-ay+az
2a(x-3y+2z)=2ax-6ay+4az
-6(2/3x-1/2y+1/4z)=-12/3x+6/2y-6/4z=-4/x+3/y-3/2z,если xyz в знаменателе, а если -6(2/3*x-1/2*y+1/4*z)=-4x+3y-3/2*z=3y-4x-1,5z
